Can tire pressure make your car shake?
Tires with lower pressure have a lower resonance frequency. When your right tire becomes under-inflated, its resonance frequency occurs at about 40 miles per hour. That natural vibration is combining with the unbalanced wheel to create a noticeable shimmy at that speed.
